WILLIAM J. SOHVVEIGER, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO HERMAN APFELBAUM, OF SAME PLACE.

FIRE-ALARM.

SPECIFICATION forming part of Letters Patent No. 489,237, dated January 3, 1893.

Application Bled July 1I, 1892. Serial No. 439,572. (No model.)

To aZZ whom it may cozwerm Be it known that l, WILLIAM J. SCHWEIGER, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a new and useful Improvement in Fire-Alarms, of which the following is a specification.

The object of my invention is to provide a concealed fire alarm within each of the several Io sleeping and other apartments of a hotel,

Steamship or dwelling, which on the outbreak of a fire will be capable of being operated from different parts of the structure to awaken all occupants and indicate thereto by printed I5 matter, caused to be exposed, the presence of fire and means for escaping.

In the accompanying drawings, Figure l is a sectional view of a portion of a hotel sufficient to illustrate the application of my inzo vention to the several rooms thereof, and means for operating the same from different parts of the structure. Fig. 2 is a side elevation of an alarm instrument, the casing therefor being shown in section and set in a wall.

Fig. is a front elevation of the same, certain parts being omitted. Fig. 4 is a front elevation of the lower portion of the same, and showing the door open. Fig. 5 is a detail.

A designates apartments in each of` which 3o a tire alarm instrument, B, is applied in such a manner as to he practically unobservable by a guest occupying the same.

b is a casing for the instrument and may be of any suitable material such as wood or metal.

b is a door therefor hinged at its lower edge so as to open downwardly. This door and the exposed edges of the casin g are arranged flush with the wall of the compartmentand are papered or painted to correspond therewith, and

therefore forming in appearance a part of the wall.

C is a magnet arranged to act on a lever c mounted to rock on pivots c and held normally against a stop c2 by means of a coil spring c3. This lever c is provided with a hook portion c4 adapted to engage with a resilient hook b2 secured to the door when the latter is closed.

(Z is an adjustable stop to limit the motion 5o of the door when closed to properly engage with the hook c4.

E is a make and break magnet having an armature e fulcrumed at @zand provided with a hammer arm e3 bent or looped at c around the edge of a bell, F, shown dotted in Fig. 3 55 so as to enable the hammer e4 to act on the outside of the bell. By thus arranging the magnet and its parts on the inside of the bell, and the hammer on the outside thereof, a better tone is obtained and the parts are pro- 6o tected from dust besides economizing space.

fis a resilient stop to impart the initial return motion of the armature from the magnet poles.

g is a light coil spring to hold the armature spring e6 in contact with the stop e7.

H is a spring, of which there may be two, if desired, serving to impart the initial opening motion of the door when the latter is released from the hook c4. After being forced 7o outwardly the door will fall in a downward position by gravity and display printed matter as shown in Fig. 4.

I is an incandescent lighting lamp of ordinary construction secured to the door b adjacent to the hinges thereof, and connected by expanding coils of wire i to the binding posts t" which are connected by wire to the binding posts jj respectively.

7o is a wire extending from the binding 8o postsj to the magnets C and thence by wire 7o to the postj.

Z is a wire connected to the wire 7c and extending through the magnet E to the fulcrum e2 which is in electrical connection with a wire 85 Z connected to the wire 7a.

m nt are the main circuit wires connected respectively to the posts j j.

The magnets C and E together with the lamp I are preferably connected in multiple 9o arc as shown and will be simultaneously operated to respectively cause the opening of the door, the ringing of the alarm bell and the lighting of the lamp whereby the printed matter may be read, on an alarm of fire.

The positioq of t-he lamp in Fig. 3 when the door is closed 1s indicated by dotted lines. N denotes hallways on the several floors, in which switches Pof ordinary construction are secured. These switches are connected to the roo main circuit wires in multiple arc, whereby any one of them, on an alarm of fire may be used to operate all the instrumentsB throughout the entire structure simultaneously.

The source of the electrical current may be derived from an incandescent lighting circuit or from a storage or ordinary primary battery Q arranged in the cellar or other convenient part of the structure.

If desired an ordinary automatic tire alarm switch may be arranged in the main circuit Wires at convenient parts of the structu re and adapted to operate to close the circuit when the heat caused by the presence of tire reaches a certain temperature. I have shown Wires m2, 'm3, extending from the circuit Wires m m of the structure, to a tire department station.

I claim:

l. In an electric alarm system as described an alarm bell for the several apartments inclosed in a casing concealed in a Wall and having a door adapted to open on an electrical alarm and display printed instructions for escaping, the said casing having an elec# tric light lamp arranged therein and capable of being lighted simultaneously with the opening of the door substantially as described.

2. In combination the bell F detachablysecured to a post extending from the casing b, the magnets E supported by the casingb and having an armature e provided with a hammer arranged to act on the exterior of the bell, and circuit-breaking mechanism as described, the latter and the magnets E being wholly inclosed Within the dome of the bell substantially as described.

3. In an electrical fire alarm system the instrument B comprising a casing let into a Wall, a door therefor provided with printed instructions in case of fire, and arranged flush with the Wall to form a part thereof in appearance, a magnet arranged to act on a catch as c to release the door, a make and break magnet as E for sounding an alarm bell, an electric light lamp secured to the door, and circuit Wires connecting the lamp and magnets to the main circuit Wires to operate simultaneously, substantially as described.

,4. In an electric fire alarm system as described, an alarm bell for the several apartments, inclosed in a casing concealed in a Wall and having a door adapted to drop on an
